Corona discharge in the steam for electrostatically enforced condensation

摘要

The corona discharge in the steam is investigated theoretically and experimentally in means of implementation with the steam condenser for the improved phase-change rate. The considered phenomena include the nucleation of water vapor on mobile charge carriers, the electrohydrodynamic vapor flow toward the condenser wall and the thermodynamics of the charged micro-droplet. The average size of micro-droplet is estimated in the dielectrophoretic model and compared with published experimental data of others. Experimental investigation of corona-supported condensation confirms the improvement in the condensation rate.
